Main Features

Useful functions of GLT400

Measure current (4 -20 mA)

Shunt resistor (250Ω) is available as an option.
Equipped with a dedicated 1-5V range for the measurement range

Shunt resistance 250Ω (B-551)
* Cannot use B-551 resistor with B-564SL input terminal

Measure humidity

A humidity sensor is available as an option.
Power for the sensor is also supplied from the main unit.
Equipped with a dedicated humidity range

Humidity sensor (B-530)

Various terminals for different applications

Various terminals for different applications. Choose based on connector type, accuracy or isolation differences.
Configure for application requirements.

(*1)

Temperature accuracy is the value when 100 °C is measured when using a K-type thermocouple (including reference contact compensation accuracy).

Terminal Base Cover (B-588)

Compatible with all input terminals
* Except using with shunt resistor (B-551)

Expandable up to 200 channels

By adding an analog input terminal and an terminal base, it can be expanded in 20ch increments from a min of 20ch to a max of 200ch.

Channel Expansion (Sample)	20ch	40ch	100ch	200ch
GLT400 main unit	1	1	1	1
Terminal base	1	2	5	10
Input terminal (*2)	1	2	5	10

(*2)

Input terminal price is means of standard terminal price.
Terminals (B-564,B-564SL,B-565) can be mixed. However, if you mix B-565 with B-564 or B-564-SL, the specification of B-565 will be equivalent as B-564 or B-564-SL.
When connected as a remote unit of the GL840 series, 180ch is the maximum. (GL840: 20ch + GLT400: 180ch) (sytem max. 200ch)

Expansion method (2 types)

The measurement data is safely stored in the flash memory of the main unit

Standard 4GB Built-in Flash memory and available SD card slot.

Internal memory : 4GB
SD card slot : Support SDHC and Max 32 GB
* SD card cannot be used when the wireless LAN unit is used.
* Max single file size is 2GB. (use Relay mode to extend recording)

Sampling Interval and Capturing time

When all 20 analog channels are being used, File size of captured data is 2GB.

Sampling interval	10ms	50ms	100ms	200ms	500ms	1s	10s
GBD Format (Graphtec Binary Data)	31 days	77 days	95 days	108 days	270 days	Over 365	Over 365
CSV Format	3 days	11 days	16 days	21 days	54 days	109 days	Over 365

*

Since the recording time is an approximation, there is a limit to the number of channels depending on the sampling speed.
10ms：1ch, 50ms：5ch, 100ms：10ch

Hot-swapping the SD memory card

SD card can be replaced during data capture when the sampling interval is 100ms or slower.

*

SD card cannot be used in the slot while the wireless LAN unit (B-568) is used.

Back up recording data

The recorded data can be automatically backed up to other storage media at regular intervals. FTP backup has a function to delete files in the main unit when the backup is successful.
Backup interval: 1, 2, 6, 12, 24 hour(s)
Backup file destination: Built-In Flash memory, SD memory card, FTP server
Data file format: GBD (binary) or CSV (text)

*

Available sampling speed is 100 ms or slower when recording in CSV format.

*

When the RING mode or external pulse synchronization sampling is selected for recording, the backup function is not available.

*

The storage device specified as the recording destination of the measurement data can not be set as the transfer destination of the backup file.

*

When backup is enabled and data file format is specified with CSV format, SD memory card exchange (hot-swapping) and RELAY recording are not available.

USB drive mode

Connect the GLT400 to PC with a USB cable and boot in USB drive mode, it will be recognized as an external drive for your PC. The measurement data in GLT400 can be transferred to PC by drag and drop.

Standard Accessory for 2 types of PC software and web browser function

Simple Operation Software "GLT400 SETTING APP"

Easily enter settings and monitor measured data from a PC. GLT400 is ideal for use with single unit. GLT400 inherited the setting screen menus from GL series.

Advanced Function Software "GL-Connection"

Max 20 units of GLT400 can be connected.
Display modes come standard with a Y-T View, Digital View, XY View and FFT View.
Contains direct Excel functions and a file connection function. Can convert GBD files to CSV format.
Show Details >

Direct Excel function installed

A function that transfers recorded data directly to specified Excel template file with recording start.
Creates a measured data file when stop recording by utilizing a computational expression and macro in combination.

Settings, control, data confirmation/transfer are possible from a PC without using dedicated software

Equipped with a WEB browser function that allows settings, control, and real-time measurement values with a WEB browser without using dedicated software, and an FTP client function that transfers files to a PC.
Supported browser : Google Chrome (Recommended), Microsoft Edge, Firefox
